Blue Book Specification for CD-Extra (formerly CD-Plus) Buffer underrun When the write memory of the drive is empty, the writing procedure will be terminated The flow of data from the system to the drive was insufficient. Either the transfer rate is too low for the writing speed or there was an interruption in the data flow. CD-DA CD-DA stands for "CD Digital Audio" and is the known audio CD standard described in the Red Book. It contains audio data that is to say music and can be played back in CD-ROM drives which support audio CDs as well as in normal CD players in stereo systems. The audio data is stored as so-called "frames" with a length of 1/75 of a second. 44, 100 audio signal samples are stored per second. Each sample uses two bytes (16 bit), and two channels are stored (left and right). This results in a sector size of 44, 1000 x 2x 2 /75 = 2352 bytes per frame which corresponds to the size of a physical block on a CD. CD-I CD-Interactive, special CD format defined in the Green Book The CD-I track is not entered into the TOC (CD directory). Thus, the audio tracks can be listened to on a normal CD player. To access a CD-I track, an appropriate drive is required. Some older CD players incorrectly recognize the CD-I track as an audio track and attempt to play it back accordingly. CD-R CompactDisc-Recordable, designation for recordable CDs CD-ROM (Single and Multisesssion) CD-ROM describes a CD which contains computer data much like a hard disk. CD-XA XA stands for "Extended Architecture" and is a standard for Multimedia CDs containing audio and computer data. GB 5 19 FREECOM Portable II Series Defragmenting A hard disk can be defragmented using the DOS command 'defrag' or a similar tool from other operating systems. Due to the fact that files are constantly deleted and new ones written to the hard disk, files are no longer grouped together in physically contiguous blocks but instead are scattered, i. e. Defragmentation rewrites the files so that they are put back together again. This does not affect the directory structure or the data contents. The advantage of defragmentation is that it allows files to be accessed quicker by simplifying the searching process. [. . . ] Audio CDs are always single session CDs. Thermal Calibration Procedure for adapting hard disks to the effects of thermal expansion. The hard disk cannot be accessed while it is calibrating. This can be a sufficient amount of time to empty the driver's buffer space. [. . . ]
